Re: Adhoc via dbus API?

Hi,

I just started using the python dbus API, but am having some
difficulties, hoping someone here might be able to help me?   (I did
find the old thread in this list with an example script but API has
changed so much that no longer works even with significant changes).

In brief:
- I can successfully configure and use an ADHOC network using (1)
manual edits of host file (after disabling NetworkManager), and (2)
using iwconfig.  
- I can create an ADHOC with nm-applette gui but cannot connect to
it.  
- What I need to do is create an adhoc with dbus but the attached
script which works perfectly to create a hotspot (with mode 'ap')
fails with bellow syslog messages when mode is 'adhoc'

It looks like it creates the connection fine and even attempts to
activate but then hits some weird authentication issue I can't debug?

Hi,


while the script is not particularly elegant (e.g. it keeps polling
whether the profile is fully activate), it should work fine in
principle. It also succeeds to create a profile, but activation fails
later on.

This has nothing to do with D-Bus API. You can create the exact same
profile with nmcli and encounter the same problem.

What I mean, is that when I try `nmcli connection up MyAdhoc`, the
activation also fails (just like with the python script).
The question is, why it fails. But I don't know...


General tip: enabling level=TRACE logging is helpful (see [1]).
Also, check what is happening with `nmcli connection` and `nmcli
device`.

Any chance someone has a working dbus API Adhoc network setup script
they could share with me?
